id-utils-3.2: description + notes

---

The id-utils package contains a collection of tools to build and query a database of tokens from text files. With this database many text-searching tasks become simpler and faster. For example, you can list all files that reference a particular '#include' file throughout a large source hierarchy, search for all the memos containing references to a project, or automatically invoke an editor on all files containing references to some function or variable.

There are several programs in the ID utilities family:

• mkid scans files for tokens and builds the ID database file.
• lid queries the ID database for tokens, then reports matching file names or matching lines.
• fid lists all tokens recorded in the database for given files, or tokens common to two files.
• fnid matches the file names in the database, rather than the tokens.
• xtokid extracts raw tokens--helps with testing of new `mkid' scanners.

In addition, the ID utilities have historically provided several query programs which are specializations of lid:

• gid (lid -R grep) lists all lines containing the requested pattern. See also "M-x gid" in emacs.
• eid (lid -R edit) invokes an editor on all files containing the requested pattern, and if possible, initiates a text search for that pattern.
• aid (lid -ils) treats the requested pattern as a case-insensitive literal substring.
